    Sluggish. Squealing. Unreliable. Vibrating. If any of these descriptors fit your vehicle’s recent behavior, it just might be trying to tell you something – like it’s time for a tune-up.

    Today’s vehicles differ significantly from their decades-old brethren that required a tune-up every 10,000 or 20,000 miles. With newer vehicles, it’s increasingly common for manufacturer-recommended service intervals to stretch to 100,000 miles before certain maintenance items, such as replacing the spark plugs, should be completed.

  • Make Your Radiator Go The Extra Mile

    Since the first automobiles, there have been radiators. Every liquid-cooled engine on the road has, and has always needed, a radiator; without it, the engine would overheat in no time, causing catastrophic engine failure. While the efficiency of radiators, the materials they’re made out of, and the shape and size of them have changed over time, radiators haven’t actually changed much over the last century or so. At Dempsey's Service Center, Inc. we know that even though radiators generally last a long time, they do occasionally fail. When your radiator is malfunctioning you can trust our technicians to repair yours and get you back on the road.
